Sinopec develops embodied-intelligence pressure-gauge calibration device
- The device calibrates four pointer pressure gauges simultaneously and generates certificates in 5–6 minutes.
- Led by Tianjin Petrochemical, the system combines robotic handling, dial recognition and software-controlled calibration.
- Reading recognition reaches 99.7%, and efficiency improves by more than 3.5 times.
- Sinopec plans to extend the technology to pressure transmitters, bimetallic thermometers and precision pressure gauges.
Automated calibration
Sinopec has developed China’s first embodied-intelligence, fully automatic calibration device for pressure gauges. It calibrates four pointer gauges simultaneously and generates certificates in 5–6 minutes, shifting the process from manual to machine measurement.
System and performance
Led by Tianjin Petrochemical, the device uses a robot to move, install and remove gauges, a vision system to centre and identify dials, and software to coordinate pressurisation, readings, evaluation and certificate generation. It improves efficiency by more than 3.5 times, achieves reading recognition of up to 99.7% and complies with national standards.
Planned expansion
Sinopec plans to extend embodied-intelligence calibration to pressure transmitters, bimetallic thermometers and precision pressure gauges. It will also promote shared datasets, evaluation methods and interface specifications, and participate in developing relevant standards.
